“The Pi 4 performs top notch. Yesterday I ran the spigot algorithm on my Pi and on my my gaming laptop (Intel Core i7-7700HQ). The Laptop is faster by only 15% with the same python code when calculating the number of pi to the 300.000 th digit. The only disappointment was the SD card: The software on it was incompatible with the Pi 4, it was written for the earlier series of the Pi.”
